So many adjustments- permutations/combinations are endless... how did you determine your set up? My length of pull was too long.. came back from the range today with a 1cm slash on my check... I was at the end of my check riser and the recoil from the308 opened me up.... stock is now broken in! ?. I’m 6’ 35” sleeve - I installed the larger LOP spacer but will go back tomorrow... how did you determine 1) LOP; 2) Butt pad angle, and 3) Butt pad height for prone... thoughts, photos welcome. Thanks for your help!
